So it does

rust-lang/docs.rs/blob/e54f601162f3e25688b6a0d5d9f376b534ca5576/src/web/features.rs#L144


      
          #[test]
          fn test_feature_map_filters_private() {
              let private1 = Feature::new("_private1".into(), vec!["feature1".into()], false);
              let feature2 = Feature::new("feature2".into(), Vec::new(), false);
          
          
    let raw = vec![private1.clone(), feature2.clone()];
              let feature_map = get_feature_map(raw);
          
          
    assert_eq!(feature_map.len(), 1);
              assert!(feature_map.contains_key(&feature2.name));
              assert!(!feature_map.contains_key(&private1.name));
          }
          
          
#[test]
          fn test_default_tree_structure_with_nested_default() {
              let default = Feature::new(DEFAULT_NAME.into(), vec!["feature1".into()], false);
              let non_default = Feature::new("non-default".into(), Vec::new(), false);
              let feature1 = Feature::new(
                  "feature1".into(),
                  vec!["feature2".into(), "feature3".into()],
                  false,

I forgot we added that. Glancing at it again I realise we don’t properly support dep:, we will still list the optional dependency as being available as a feature even if it has been disabled. Fixing that might need more info from cargo-metadata, I’ll try to take a better look and open an issue later (along with one about supporting the document-features syntax).
